a^{2} + (- 1.19 a)^{2} = 7

a = \frac{700}{24161}, a = - \frac{700}{24161}

Decimal Notation

a = 4.50340 \dots, a = - 4.50340 \dots

Solution steps

a^{2} + (- 1.19 a)^{2} = 7

Square both sides:

2.4161 a^{2} = 49

2.4161 a^{2} = 49

Solve

2.4161 a^{2} = 49 : a = \frac{700}{24161}, a = - \frac{700}{24161}

a = \frac{700}{24161}, a = - \frac{700}{24161}

Verify Solutions:

a = \frac{700}{24161}

True

, a = - \frac{700}{24161}

True

The solutions are

a = \frac{700}{24161}, a = - \frac{700}{24161}

x = 2 x - x^{2}

\frac{m}{10} = 10

x = 4 + 5 x - 26

3 x + 1 = 2 x + 6
